Hi all, just wondering if there's a trick out there for holding the bolt head inside front spring hanger while undoing nut on outside. Can't get a spanner in there. Suppose cutting wheel will do the trick but is there a less drastic way?

Did try that but nut is fairly tight/rusted so not much luck. I could probably grind some scrap steel to size to wedge between head and side of hanger (edit: between head and floorpan I think ) Cheers.

Well I got one off by poking bit of steel in to wedge bolt and the other one did not want to play that game so a good grinding was in order there. I think I have used grinder more often than the spanners on this strip down.
